CONCRETE MIXER AND CONVEYER.

Specification of Letters Patent.

Application filed March 26, 1908.

Patented July '7, 1908.

Serial No. 423,293.

To all whom it may concern:

Be it known that I, JOHN B. THIEs, citi- Zen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Concrete Mixers and Conveyers and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the ac companying drawings, and to the letters and Iigures of reference marked thereon, which form a part of this specification.

This invention comprises a combined concrete mixer and conveyer.

` The object of the invention is to provide a manually-operative machine for concrete work and in which the concrete is mixed while being conveyed in the machine to points where it is to be used.

In the accompanying drawings-Figure 1, is a side elevation of the machine with one of the side plates and one of the handles removed. In this figure, the two positions of the machine are shown, one being the con- .veying position during which the concrete is mixed, and the other position being the position of the machine when the concrete is being delivered. Fig. 2, is a top plan view of the machine.

In a detail description of the invention, similar reference characters indicate corresponding parts.

The two side plates l 1 are preferably made of sheet metal and besides forming the side inclosures of the machine they form a wheel, the axle 3 being that upon which the said sides rotate.

4 4 designate washers secured to the outer sides of the plates and form bearings for the shaft 3.

The peripheries of the side plates 1 l are provided with serrations 2 which impart to the concrete a constant jolting (hiring the movement of the machine. The concrete is delivered from one to the other of a series of buckets 5 arranged between the side plates and attached thereto. These buckets are arranged substantially as shown in the drawings with the ,innerend of each bucket occupying a position from the axis of the machine about one-third of the entire distance from the axis to the periphery of the machine It is essential that this arrangement of the bucket shall be observed and that three of such buckets shall be used. In such arrangement of said buckets, the inner end of one bucket forms the center of a circle of which another bucket is an arc. Such an arrangement of the buckets is necessary in providing such a series of receptacles that will properly receive the concrete from one receptacle to the other in the rotation of the machine, as in moving it over thc ground. The inner end of each of the buckets 5 has a baffle plate 6 which throws outwardly the concrete from the uppermost bucket in a manner to turn it over as it is delivered from each uppermost bucket.

Fulcrumed on the axle 3 outside of the side lates of the machine are two bars 7, the iront ends of which are provided with handles 8 to be gripped by the operator in transporting the machine from point to point. These bars are united infront of the machine by a tie rod 9, and in the rear of the machine they are united by a cross bar 10 which has a foot ll midway of its length. This foot l1 supports the machine when the handles S are moved up to a perpendicular position as in the dotted position in Fig. l. When the machine is in that position, the sides, together with the buckets, are turned by hand backward or in the direction of the arrow which is shown in broken lines. In turning the machine in that manner, the concrete will be delivered from the buckets to the ground with no obstruction. It will be understood that when the machine is being conveyed to the points of distribution, it is rotated in an opposite direction or in the direction indicated by the arrow shown in full lines. When thus operated, it rolls over the ground and the corrugated edges of the side plates constantly jolt the concrete and prevent it from adhering to any extent to the buckets.

It will be understood that the concrete is mixed in the machine during its propulsion. The proper proportions of the material are placed in one of the buckets and the machine is then rotated by means of the handles. Each complete rotation of the machine turns the concrete over three times, so that it becomes thoroughly mixed in one rotation.

I claim:

l. In a machine of the type specified, two annular side plates, a series of curved buckets secured between said side plates, the inner end of each of said buckets being located from the axis of the machine a distance of about one-third of the entire distance from the axis to the periphery of the machine, battle plates on the inner end of each of said buckets, a handle pivoted to the axis of the machine and providing means for propelling the machine as well as means for supporting the machine in a position for the concrete to be delivered therefrom.

2. A machine of the type s ecified comprising two annular side plates aving corrugated peripheries, a series of three buckets secured between said side plates in ositions with the outer ends of said buckets ying adjacent to the periphery of the side plates and the inner ends of said buckets lying away from the axis of the side plates about onethird of the entire distance between the axis of the side plates and the periphery, the. in-

ner ends of said buckets having baille plates terminating at an angle thereto, and handle bars attached to the axis of the machine and extending beyond the periphery in two directions, said handle bars providing means for propelling the machine and for supporting it in a position for the concrete to be de1ivered therefrom.

In testimony whereof I aiiix my signature7 in presence of two witnesses.

JOHN B. THIES.
